Fatented June 14, 1932 UNITED STATES HARRY S. HART AND DAV ID HINDAHL, OF CHICAGO, ILLINOIS, ASSIGNOES I HARRY S. HA.RT, OF CHICAGO, ILLINGIS can cous'muc'rron Application filed March 13, 1929. Serial 110,346,559.

This inventionrelates to an improved construction for railroad cars, and has particular application to railroad cars of the hopper or gondola types or other cars which carry materials offering severe wear and corrosive effects to the side sheets or side stakes and other similar parts in use.

An object of this invention is to provide a car construction which has a maximum ca- 1e pacity for its dimensions, and is of such chartion, and simple both in design and manner acter that it has great resistance to wear and deterioration in use.

Another object is to provide a car co struction which is highly eflicient in operaof assembly andis one the maintenance of which is economical, as the parts likely to wear are relatively cheap and easy to replace, whereas the more expensive and less acces- 29 sible parts are constructed and arranged so as to resist and be spared destructive and detrimental wear. v

The present invention is illustrated as applied to a hopper car and accordingly it is another object of the invention when the invention is so applied to provide certain novel features of construction such as construction of side stakes and similar parts which make for great improvements in hopper. cars.

Various other objects not specifically enumerated are contemplated. and these will readily appear to one skilled in the art as the following description proceeds.

Although the invention is disclosed as embodied in a hopper car the present disclosure is given merely by way of illustration and is not to be construed as limiting the invention in any particular.

The nature of the invention may be determined from an understanding of the illustrated form and an appreciation of the advantages which it produces in such an embodiment.

The particular disclosure and the invention will be more readily understood from the following description when considered in connection with. the accompanying drawings in which;

- T Figure 1 is a side elevational view of one spective views showing end of a hopper car constructed in accordance with the present invention.

' Figure 2 is a transverse plan view of the construction shown in Figure 1 taken on the line 22 and looking in the direction of the arrows.

Figure 3 is an elevational view in trans-' 1, and looking in the direction of the arrows.'

Figures 4 to 8 inclusive are enlarged perstruction of the car si the present invention. v

By referring to the drawings, it will be noted that this invention is disclosed as embodied in a hopper car having the usual under frame 10, with a body bolster 11 adapted to be mounted on a truck not shown, but the location of which is diagrammatically represented by the outline of the car wheels 12.

The body of the car is illustrated as being of the hopper type and comprises upper chord members 13 and lower chord members 14 connected by the vertically arranged stakes hereinafter more fully described. At the end of the car the end stakes 15 are provided which are illustrated in the form of an stakes employed in angle bar but which may be of any suitable shape. The fioor of the car comprises the slope sheet 16, extending from the end of the car down to the hopper outlet 17, the car also being provided with a slope sheet 18 on the opposite side-of the hopper.

Inasmuch as the opposite. end of the car is of duplicate construction to that shown in the drawings, only one half of the car will be herein disclosed and described as such description will completely show the features of this invention.

Theside stakes are out special construction and are preferably formed of cast steel or some other similar non-corrodible substance whereby they will not be subject to Wear and deterioration due to their wearing contact with the eontentsor material carried by the car in use. i

Accordance to this invention, the car takes throughout the larger and intermediate portions of their length, are disposed inwardly the details of conof the side sheets are disposed diagonallyinwardly so as to form upper and lower shedding surfaces as well as to permit the location of the end portions of the side stakes to be outside of the walls of the car in such manner that the means connecting the ends of the stakes with the upper and lower chord members are protected against the corrosive eflect and detrimental wear of the material carried by the car in use. The arrangement is also designed to eliminate at both the top and bottom edges, any flanges such as will be apt to catch and collect the material carried in the ear in a manner to prevent complete discharge of all of the material in the car and also to eliminate any ledges or flanges on which buckets or other tools may be caught on entering and leaving the car during a loading or unloading operation.

The fact that the side sheets throughout the larger portion of the car are located in a plane outside of the ear stakes, it will be appreciated that a maximum capacity is provided for any given dimensions and yet the detrimental effects of such constructions are eliminated by the provision of the non-corrodible steel stakes of the special construction contemplated in this invention.

By referring to Figure 1 it will be observed that stakes 19, 20,21, 22 and 23 are provided, all of such construction, as to form means for attaching the side sheets in the manner contemplated in this invention, and as illustrated in detail in Figures 4 to 8 inelusive.

In the present illustration, the upper chord member 13, is in the form of an angle iron having a downwardly depending flange 24 vertically disposed and a horizontal flange 25, this latter flange being illustrated as having a reinforcing beading, 26, on the outer edge thereof. The lower chord 14, is also an angle bar disposed vertically below the upper chord 13, and having the vertical flange 27 in the same plane as the flange 24, above referred to. 7

Referring now to the side stake 19, it will be noted that this stake is located cent-rally of the car and it is to be understood that depending upon the car construction, there may be one or more stakes of this general construction. The upper end of stake 19 is constructed in accordance with the showing in Figure 4 and provided with an outer flange 28, and an inner flange 29 connected by the intermediate web 30. The outer flange 28, is of greater width than the inner flange throughout the main body portion of the stake.

Extending diagonally across the stake are flanges 31, which are in efleet, continuations of flange 28, these last named flanges finally extending vertically to form flanges 32 lying in the plane of the inner flange 29. A top flange 33, is provided, extending horizontally and providing means for attachment of the stake to the horizontal flange 25, of the upper chord member. The web portion 30, continues upwardly, passing through the diagonal flanges 31 and is provided with an end flange 34, which lies substantially on the same plane as the flange 28. The stake is provided, however, on its outer surface with the step portion 35 which is provided as a preferable construction when the upper portion of the side sheets are made separate from the intermediate vertical portions, this step serving to accommodate the end of the upper portion in the manner shown in Figure 3.

The lower port-ions of side stakes 19, are formed in accordance with the construction shown in Figure 5, wherein it will be noted that the inner flange 29, flares outwardly to form a wider flange 35, adapted for attachmentto the vertical flange 27 of the bottom chord. The outer flange 28, diminishes in width as at 36 whereby a reinforcement is formed on the edge of the web portion 30.

Referring now to stakes 20 and 21 which in the present illustration are of similar construction but it will be appreciated that de-- pending upon the car construction, any'desired number of stakes of this construction may be employed. Stakes 20 and 21 have their upper ends formed in accordance with the construction shown in Figure 4, or in other words, of exactly the same construction as that of stake 19, but the lower ends of stakes 20 and 21 are constructedin accordance with the showing in Figure 6.

In Figure 6, the view is from the inside of the car or in other words. the reverse side from that shown in Figure 4. Here it will be noted that the inner flange 29 at the lower portion. extending diagonally inwardly as at 37 and that the web. 30 is enlarged to form a projecting reinforcement with the flange 37 for the diagonally disposed flanges 38. The flanges 38. are in a sense. a continuation of the outer flanges 28 and are adapted to receive the bottom portions of the side sheets which extend inwardlv in a manner to form shedding surfaces. The stake, however, continues vertically downwardly and is provided with an enlarged flange 39, on the inner surface of the web 30, and a reinforcing flange 40' on the outer edge of the web 30.

The flange 39 is adapted to be secured to the vertical flange 27 of the bottom chord whereby the diagonal flanges 38 are disposed in tle proper relationship as shown in Figure Referring now to stake 22. it will be noted that the upper end of this stake is constructed in accordance with the showing in Figure 4, whereas the intermediate and lower portions thereof are constructed in accordance with the showing in Figure 7. The showing in Figure 7 is a view from the inside of the car and it will be noted that that portion of the stake which projects below the slope sheet 16, is merely in the form of a modified I-beam having its inner flange slightly larger than the outer flange so as to form as at 41, means for attaching the lower end of the stake to the flange 27 of the bottom chord. At the locationwhere the stake crosses the diagonal plane of the slope sheet, diagonally disposed-shelves 42, arranged on opposite sides of the web 30, are provided so as to receive and form means for supporting the slope sheet 16. Above. t-hisplane however, the outer flange 28 is enlarged and forms means for receiving and supporting the side sheets. and the flange 29 on the inner surface is presented in a manner similar to the corresponding portion of the other stakes.

Referring now to stake 23. this stake is constructed in accordance with the showing in Figure 8 whereby it will be noted that it is of a modified I-beam construction at its upper end and of Z-bar construction throughout the intermediate portion of its length. The upper portion is provided with a diagonally arranged flange 43 on one side terminating in the vertical flange 44 which lies in the plane of the surface of the stake. On the same side ,of the stake, the flange 45 is provided lving in the plane of the outer surface of the stake. This flange, together with the flanges 43 and 44 corresponds with the flanges 28 and 31 of the other stakes for receiving and supporting the side sheets.

At the location where the slope sheet 16 crosses the stake, a diagonally disposed shelf 46 is provided for the purpose of supporting the slope sheet in a manner similar to that described in connection with the shelves 42 on the stake 22. The opposite side of the stake is provided with a flange 47 extending vertically in the plane of the inner surface of the stake throughout the entire length of the stake. this flange constituting means for supporting the side sheet at the location of the ladder recess at the end of the car. This recess is shown in Figure 1 at 48. The upper end of the stake is also provided with a horizontal flange 48, corresponding to the flange 33 on the other stakes and in addition is provided with a step 49 of similar construction and for the same purpose as the step 35, shown in Figure 4.

The lower end of the stake throughout that portion which. extends below-the slope sheet, serves merely as a support having its inner flange enlarged whereby at its bottom portion 50, it will serve as means for attaching the stake to the vertical flange 27 of the bottom chord.

Throughout the entire assembly, rivet holes 51 are provided in the stakes, chord members and side sheets to serve as means for attaching the side sheets, by the rivets 52.

As shown in Figure 1, throughout the intermediate portion of the heighth of the car, a single side sheet 53 is provided in the vertical plane, attached outside of the stakes on the flanges 28 and 45. At the upper portion of the wall of the car, diagonally disposed side sheets 54 are provided, connected to the diagonally disposed flanges 31 and 43 by means of rivets 52 and rivet holes 51.

The side sheets 53 and 54 are adapted to overlap as at 55 and are provided with registering riveting holes 51 for receiving rivets 52 for securing the sheets together. At the lower location, side sheets 56 are provided between certain of the stakes, secured to the flanges 38 by means of rivet holes 51 and rivets 52 so as to form in effect, shedding surfaces inclined toward the hopper opening. Sheets 56 overlap the lower edges of sheets 53 and are secured by means of rivet holes 51 and rivets 52 as shown.

It.is to be understood that side sheets may be of any suitable shape, that is, they may-be made up of a plurality of independent sheets or formed of one continuous sheet. This latter form also includes the formation of sheets 53, 54 and 56 as an integral sheet. It is obvious that the manner of providing these sheets, that is whether they be a unitary sheet or independent sheets, does not affeet the spirit of the invention and accordingly the invention is not to be limited in this particular. However, one preferred form is illustrated in the drawings.

The side sheet, 57, is secured by rivets 52, to the flange 47 on the stake 23 and to the flange 58 on the end stake 15. Here again it will be appreciated that this sheet may be inde pendent or integral with the other side sheets if it is desired and without departing from the spirit of the invention.

, It will be appreciated fromthe above description that this invention provides a novel and improved car construction which will have a maximum capacity and is one in which great durability is provided, inasmuch as the stakes are formed from steel, they will offer face, provided by the side sheets 54, permit a free passage of thematerial out of the car without interference when the car is tipped in vdumping cradles such as are used in unloadin cars of this type.

- t will further benoted that the frame construction including the stakes and chord members is of strong permanent construction and that the parts are so constructed and arranged that the side sheets only will be subject to wear and that these may be readily removed and replaced without undue trouble and expense.

In the up-keep of cars of this character, the side sheets are the least expensive portion and it is contemplated that these will be damaged by wear and replaced from time to time, and accordingly acting on this understanding the present construction provides a permanent frame of great durability and means for permitting the ready and inexpensive removal of the old side sheets and attachment of the new side sheets.
